Grothendieck duality and Q-Gorenstein morphisms
Yongnam Lee, Noboru Nakayama
The notions of -Gorenstein scheme and of -Gorenstein morphism are introduced for locally Noetherian schemes by dualizing complexes and (relative) canonical sh…
Simply connected surfaces of general type in positive characteristic via deformation theory
Yongnam Lee, Noboru Nakayama
Algebraically simply connected surfaces of general type with p_g=q=0 and 1\le K^2\le 4 in positive characteristic (with one exception in K^2=4) are presented by using a Q-Gorenstei…
Polarized endomorphisms of complex normal varieties
Noboru Nakayama, De-Qi Zhang
It is shown that a complex normal projective variety has non-positive Kodaira dimension if it admits a non-isomorphic quasi-polarized endomorphism. The geometric structure of the v…
Building blocks of etale endomorphisms of complex projective manifolds
Noboru Nakayama, De-Qi Zhang
Etale endomorphisms of complex projective manifolds are constructed from two building blocks up to isomorphism if the good minimal model conjecture is true. They are the endomorphi…
